A cable tray is a physical unit that supports and routes cable.
Cable Tray Run
A cable tray run is a connected series of cable tray features that normally have the same specification. Cable tray features belong to a corresponding cable tray run.
Cable Tray Barriers
You can use barriers to divide a cable tray into lengthwise partitions. Each partition is treated as a separate cable tray, so that you can route cables of supported signal type. The following illustration shows how one barrier creates two partitions and two barriers create three partitions and so on. Smart 3D reports all the cables it supports, as well as the cumulative loads of all the zones.
Enclosing Run and Enclosed Run
To modify a cable tray partition, select Enclosed Runs from the Locate Filter. To select an entire cable tray, select Enclosing Runs.

Cable Tray Features
When you are routing cable tray, the software automatically selects the specific parts for the features based on the specification of the run. You may freely move features about at any time during the design process.
The following illustration shows a cable tray network and some of its features.
As the cable trays are modified, cable lengths are automatically adjusted. When new cables are added, the fill of the cable tray is calculated. You can view the maximum fill on the ribbon or the Properties dialog for straight features. When you click the MaxFill command, the software highlights the portion of the cable tray with maximum cable fill.
Cable Tray Covers
Cable tray covers are used to prevent the personnel from touching the cables and safeguard the cables and cable trays from damage in extreme climatic conditions such as:
-
Prevention of snow accumulation on the cable trays.
-
Protection of power cables from direct exposure to the sun to avoid overheating.
The covers on the cable trays can be defined with an offset distance from the start point of cable tray parent part. The covers can be added and deleted using the cableway feature property dialog. The covers can be modified using Cable Tray Cover Part Properties Dialog. You can also generate a report for cover properties.
